EC3015 - 15Amp Circuit Breaker

EC3015 - 15 Amp Circuit Breaker

The EC3015 circuit breaker is a 3-pole, 15-amp thermal-magnetic molded case circuit breaker designed for dependable overcurrent protection in electrical distribution systems operating at up to 240VAC. Built on the EC frame platform, this breaker features a non-interchangeable trip unit and is calibrated for 40°C ambient conditions, making it suitable for standard commercial and industrial electrical environments. Its thermal-magnetic design responds to both sustained overloads and instantaneous short-circuit events, helping protect conductors and connected equipment from damage. The EC3015 is commonly used as a form-fit-function replacement in compatible legacy panelboards and distribution equipment where EC-frame breakers are specified. Load terminals are included, simplifying installation and ensuring proper conductor termination.

Engineered for consistent operation, the EC3015 offers the dependable switching and circuit protection expected in molded case breakers designed for long service life. Its 10kA interrupting rating at 240VAC supports safe interruption of fault currents within rated systems, while the three-pole configuration allows protection of multi-phase circuits. Whether used in maintenance projects, facility electrical service work, or equipment replacement, this breaker helps maintain safe operation in existing electrical systems where EC-frame devices are required.
